The Zach-Frankie scenes have been something new for the reality genre, because Zach displays a groundbreaking comfort with his sexuality. Is he really that way or is he playing a game?

The Zankie "showmance" has helped "Big Brother" score this season in the ratings. All three episodes placed in the Top 10 in total viewers last week. Those three episodes ranked among the Top 5 with the 18-to-49 age group.

Zach will have a chance to open up in the exit interview with Julie Chen. Will he go quietly? What does he really think of Frankie? The show starts at 9 p.m. on CBS (WKMG-Channel 6).

In the end, Frankie put the game first and says he thinks Zach hurt his game. So much for "showmances," whatever variety they be.

Can Frankie win it all when "Big Brother" names a winner Sept. 24? Probably not.

Police sergeant Derrick is the favorite because he has played the smartest game. That could change if his close ally Cody is ejected.

There's little doubt which player is the public's favorite. Donny, the bearded, kindly school groundskeeper, repeatedly wins raves from departing house guests.

But Zankie sure helped "Big Brother" go this summer: It was something new for television. And how often can you say that about reality TV?
